ARRANGEMENT FOR RECEPTION OF ELECTRIC IMFULSES AND FOR CONTROLLING THE ORIENTATION OF COMMUTATORS Original Filed Dec. 18. 1926 5 Sheets-Sheet 3 Fig. 2 a} Patented Feb. 11, 1930 UNITED STATES PATENT OFFICE ANTOINE BARNAY, OF PARIS, FRANCE ARRANGEMENT FOB RECEPTION OF ELECTRIC IMPULSE AND FOR CONTROLLING THE ORIENTATION OF COMMUTATOBS Application filed December 18, 1926, Serial No. 155,745, and in France December 18, 1925. Renewed October 26, 1929.

The present invention has for its obj an arrangement for reception of electric 1mpulses and for controlling the orientatmn of a commutator.

In arrangements of this kind the impulse receiver and the commutator each comprise contacts, the corresponding contacts of the re ceiver and the commutator being interconnected. The number of receiver contacts is equal to the maximum number of lmpulses which may constitute a series of impulses.

The ob'ect of the invention is to diminish this num er of contacts. Thus, in an arrangement contrived to receive ten impulses this invention will permit the reduction to three or four for example of the number of receiver contacts.

The invention is characterized in that each receiver contact is connected to several nonconsecutive controlling contacts of the commutator, the consecutive contacts of this commutator being each connected to the contacts actuated successively by the successive impulses and being of a number less than the maximum number of impulses which may constitute a series of impulses. I

For example, if the receiver comprisesfour contacts actuated in the order l2-.34 1-234-12 (for ten impulses) and if the commutator comprises ten controlling contacts IIIIII-IVV-VI VII V'III1X-X, the contact 1 is connected to the contacts IVIX, the 2 contact with the contacts IIVIX etc.

The accompanying drawing shows by way of example only three embodiments of the invention.

Fig. 1 is a diagram of the principle of the circuits forming the subject of the invention.

Fig. 2 is a diagram of the application to a group selector utilized in telephony which may be of a type described in French Patent No. 570,941 and its additions.

Fig. 2 is a variant of this diagram.

Fig. 3 is a diagram of the application to a line selector of the type described in the said patent.

In Fig. 1 a commutator constituted by the wiper 1 and ten groups of contacts I-X which may be explored by the wiper 1 is set in operation by a propulsion electro-magnet M.

The circuit of the electro-magnet M is controlled by the contact 2 which is opened on the energization of the relay 3. The said relay 3 brings about by its energization the arrest of the movement of the wiper 1 on one of the contacts I-X; the circuit of this relay is closed by earth, one of the contacts 456-7, one of the contacts I-X, the wiper 1, the winding of the relay 3 and battery.

The contacts 4-5-6-7 are closed respectively and periodically by an impulse receivmg system (rotary commutator or relay which responds to the action of trains of electrical impulses; the contact 4 being closed on the first impulse, the contact 5 on the second, the contact 6 on the third, the contact 7 on the fourth, the contact 4 again on the fifth, the contact 5 on the sixth etc., in such wise that one of the contacts 4567 alone remains closed at the end of the train of impulses, this contact being determined by the number of impulses sent.

The number of the contacts 456. or 7 is, in accordance with the invention, always less than the maximum number of impulses which may constitute a train.

The wiper 1 pauses after the contact 4 is opened, after the first impulse, and stops every time the wiper 1 arrives at a contact IX earthed by way of 456 and 7.

In order that there may not be a false orientation of the commutator, for a given series of impulses, it is requisite that the wiper 1 should have left the group of contacts previously connected with the group Wanted before this group is earthed by the contact 456 or 7 corresponding to the series in question.

For example, if the number of impulses sent be six, the earth will be connected by way of 5 with the contacts IIVI and X, and, in order that there may not be a false connection, it will suflice that the wiper 1 shall have left the group of contacts II before the earth is reconnected at 5 on the conclusion of the periodical closure of the contacts of the receiver.

' operative by means which form no part of the -11 is energized by: 11, 12, 13, 14, 15,16, 17 and closes 4; the earth is connected to the contact groups I, V and IX of the commutator by 18, 19, 4 and at 3 which is. energized,

Given the speed of the commutator and the incidence of the impulses it will always be possible to determine the number of contacts such as 4-5-67 inorder thatthe condition explained above may be fulfilled.

In the selector of Fig. 2 the impulse relay 8 is normally energized when the selector is subject of the invention. The relay 9 is energized by +earth-10, winding of 9 and battery. The current impulses sent by a calling station will have" for effect to interrupt the circuit of the relay 8 which will be\ de-energized on each occasion; the slow relay 9 remains held in in spite of the brief interru tions of its circuit at 10.-

n the first de-energization of 8 the relay across the wiper 1. On the first re-energization of 8 (end of the first impulse) 20 1s energized by: +earth, 18, 19, 4, 20 and 11in series,

- 'battery. v

On the second de-energization of 8, 21 is excited by :-battery, 21, 22, 13, 14, 15, 16, -17, +earth; earth is connected to II, VI and X by 18, 23 and 5. On the second re -energ1zation of 8' (end of the second impulse) 24 is energized by: +earth, 18, 23, 5; 24 and 21 in series, battery.

The relays 11 and 20 have their circuit dis.-

connected at 19 and the electro-ma net M has its circuit closed by: -battery, 25,- 2, 26, 18 and +earth. The commutator pauses an can thus get the contacts of the group II.

On the third de-en'ergization of 8, 27 1s energized by battery, 27, 28, 14, 15, 16, 17 and +earth. Earth is connected to the groups III and VII by 6.

On the 3rd re-energization of 8, 29 is energized by: +earth, 18, 30, 6, 29, 27 in series and battery; 24 and 21 release andearth is cut out at II. I

On the 4th de-energization of 8, 31 is energized by: battery, 31, 32, 15, 16,17, +earth; earth is connected to IV and VIII by 7. On the 4th re-energization of 8, 33 is is excited by: +earth, 18, 34, 7, 33 and 31 in series and battery; 29 and 27 release and earth is cut out at III.

On the 5th 'de-energization of 8, II is excited again by: "battery, 11, 12, 35, 16, 17, +earth; earth is cut in at I, V and IX by 4. At this moment, thewiper 1 has already left the group I and can only stop at V. On the 5th re-energization of 8, 20 is re-energized by: +earth, 18, 19, 4, 20 and 11 in series and -battery; 33 and 31 release, and earth is cut out at IV and VIII.

The following de-energizations of 8 and its re-energizations thus act periodically on the relay groups 11-20, 21-24, 2729, 31- 5 earthing ggriodicall the contacts I-V-IX, II-VI- III II, IV-VIII. The electro-magnet M, the action of which is con trolled by 2, which acts under the influence of the relay 3, is constantly earthed, from the end of the first impulse, by one of the contacts 36, 26, 37 or 38 and 18. V

The slow relay 39, energized on the first impulse in parallel with 11, holds until the last im ulse, and returns to rest at this instant. en the-impulses are termined, and after the wiper 1 has reached the first contact of the group wanted, the rela 3 is energized in a circuit such as described above and disconnects at 2 the circuit of M, which arrests the wipers.

Two circuits are then completed, one, for actuating the wipers for hunting for an idle line by; +earth 18, a contact such as 38, a contact such as 4, a grou of contacts such as V, 40, 41, 25 Mand battery; the other, the test circuit, by: 42, 43, lower winding of 44-testvwiper 45 and the poleon a test contact when this wiper finds an idle line 'ch'ar- 'acterized by the presence of this potential on the test contact. The test relay 44 arrests the movement of the wipers by opening the circuit of M at 25.

The remainder of the connecting operations has no relation to the invention.

The definitive de-energization of the relay 8 at the end of the call causes the release of the relay, which opens all the relay circuits in working position.

All'the wiper switch devices described in Patent 570,941 and its additions may be utilized,-as is understood.

Likewise,' the groups of relays 11'20, 2124, 2729, 31- 34 may be replaced by single double-acting relays.

In Fig. 2" the groups of lines of the selector are arranged tog'ive the commutator a longer time to move between two series of contacts marked simultaneously by the relays which receive impulses. This arrangement permits, in turn, reduction of the number of these relays.

With this object, the groups of contacts such as I, II etc., in the selector are divided into two parts; one comprising a single contact I, II, III etc. (the first of each group) is normally connected to the corresponding contact actuated by the impulse receiver; it is this contactwhich determines, by being earthed, the orientation of the wipers of the group selector on the group wanted; the other comprises all the other contacts of the group (IIIIII' etc.) normally interconnected and connected to the first contact of their respective group only after the orientation of the wiper actuated by the impulses; these contacts act to permit the hunting for an idle line in the group under consideration.

In this way it will suflice that the wiper 1 has passedbeyond the first contact of a group relative to Fig. 2,

instead of all the contacts of the'group as in the preceding case before this group is marked again by the following closure 0 the corresponding contact such as 4.

It will be easy, referring to the description to follow the opera ion of this selector; the only difference resides in the energization of the relay 46 after the end of the series of impulses (release of 39) and after the orientation of the wiper 1 on the group wanted (-energization of 3). The relay 46 is excited by earth, 42, 47, 46 and battery; the relay 46 closes the circuit of rotation at 41 and connects, respectively, by 48, 49, 50, 51 the first contacts I, V, IX; II, VI, X; IIVII, IVVIII of each group to the other contacts I, V' IXII-VI'- X, IIIVII, IVVIII' of these groups.

The line selector of Fig. 3 is oriented by two successive series of impulses each acting on the same set of impulse receiver relays; the first series (tens digit) orientates the wiper 1 on the first line of the ten chosen, the second series (units digit) on the line selected in the ten wanted.

On the sending of the first digit, the relay 8 acts on the relays 1120, 21-24, 27-29, 31-33 as indicated for Fig. 2. On the other hand, as soon as 9 is energized, 52 is energized by; battery, 52, 53, 16 and earth. The relay 52 selects the group marking lines on the first contacts of each ten in the commutator by 54, 55, 56 and 57.

The tens I and II, III and IV, V and VI, VII and VIII, IX and X are marked respectively by the same contacts, a commutation relay 58 permitting the choice of one or other wiper set in accordance with the ten demanded as indicated in Patent 570,941.

When the impulses corresponding to the tens digit are terminated, the relay 37 releases, and, according as the number of impulses sent is odd or even, the relays 11 or 27 on the one hand, 21 or 31 on the other hand,

are energized, and the relay commutation circuit 58 is closed in the second case only by; earth, 18, 59, 60, 61 or 62, 58 and battery. The relay 58 locks up by 63 and 18 and substitutes the set of wipers 65 for 64 by means of 66.

When the wiper 1 reaches the first tens line wanted, the relay 3 is energized as previously described, and opens at 2 the. circuit of M. The holding circuit of the relays 11, 20, 21, 24, 27, 29, 31, 33 kept closed until now, either by 67 (during the impulses) or by 68 (until the orientation of 1) is then opened and these relays release. The relay 69 earthed by: 18, 67, 70 is short-circuited until all the relays which receive impulses release by: earth, 18,71, 72 and one of the contacts 73'to 76, 77. This short-circuit is broken at 73, 74, 7 5 or 76 when the relay 33, 29, 24 or 20 releases and 69 is energized; 69 is locked up by 18 and 7 9 and prevents a new short-circuit by the opening of 77 The relay 3 remains locked up un--.

til now by: earth, 18, 71, 72 and 78. The relay 52 has its circuit opened at 53, and switches the marking lines on to the .units control contacts by: 80, 81, 82, 83. Further, the tenscontrol contacts are connected to the units marking line 1 by 84 and 85.

The second digit acts in the same manner as the first and at the end of the definitive orientation '39 is at rest and 3 at work.

A test circuit is closedby: earth, 18, 86, a contact such as 38, 87, 88, 89, 90, the two windings of the test relay 91, 66, wiper 65 and test' contact of the line called. .A circuit for the relay 92 is closed by: earth, 18, 71, 72, a contact such as 73, 93, 92 and battery. If the line is idle, the relay finds the pole on its test contact, is energized and is locked by 94 and its upper winding before its circuit is interrupted at 90 by the slow relay 92. If the called line is busy, 91, is shunted by the plus polarity on the test contact and 92 is alone energized giving, for example, the busy tone.
